Hi Justin,
Thanks for input.
Also, we came across this link
https://stackoverflow.com/questions/9777864/how-can-i-get-the-client-certificate-in-netty-handler-to-identify-user
where it seems we can extract SSL information from ChannelHandlerContext ctx
object. Do you see if it is feasible?
ChannelHandlerContext ctx = ...
SslHandler sslhandler = (SslHandler) ctx.channel().pipeline().get("ssl");
sslhandler.engine().getSession().getPeerCertificateChain()[0].getSubjectDN());
Best Regards
Shiv

One option to improve this situation for Core [1] and OpenWire [2] clients is
to specify the "local" port which will then be printed on in broker log along
with the IP address. By default both clients use a random, available port which
makes correlation difficult, if not impossible, in my circumstances. Of course,
every client which does this will need to use a unique port to ensure there are
no conflicts if they are all running on the same machine.
Let me know where you reached out to the Netty community and I'll follow along.
Justin
